Clutch noise when engaged/disengaged
 
1 Attachment(s)
Alright,

So like many of you out there who have this issue I got my dealership to open a TAC with Chevy.

Check out the image.

This is just informational for the rest of you out there. I still don't like the noise or the answer provided but if it breaks at least a case is out there.

Is this noise while the car is sitting still? Or moving? Turning slow?

Most of them are quite clunky if clutching while rolling slow, especially if turning slow. Driveline clearances and torque suddenly released can make everything clunk. Especially with an LS diff, the clutches will be dragging a bit on slow turns and you can get a clunk/pop when everything releases. Changing the diff lube and 10 slow figure 8s can help with that.

Mine does the same thing

Slow2011SS 06-15-2011 11:30 AM

It happens when you are in motion. Slow speeds first and second gear. Sounds like the exhaust is rattling however it is not. I did some research and there are a few posts about it however they got the run around. This is simply information for those who have doubts that its normal. When it breaks we can all utilize the case number listed to have it updated with Chevy.

I thought it was strange too on the first M6 performance car I bought. Having owned many since in the past couple decades - they all do it. It's exactly what the dealer told you, driveline clearances clunking when torque is released from the driveline. Those clearances have to be there for the trans and diff to work right.

You can sometimes hear similar clunking by shutting the engine off while the clutch is out with the trans in nuetral. Also - normal.

+1....Yes, it's annoying, but every 6spd I've ever had before has been this way from day one also.

Collective driveline slack? Mine does this too from day one with 6 miles on it. IRS and 2 piece driveshaft could all be contributing.

DarkObsession 06-15-2011 12:37 PM

Mine does this too and does it even when stopped. You can also very faintly feel the vibration in the shifter when it happens.

I am going to visit my parents very soon and my dad is the service manager of a Chevy dealer (and previous to that, master, ASE certified mechanic). He is going to check it out for me and obviously, he's going to be wanting to err on the side of fixing it for me :)

I will let you all know what he finds when he checks it out.

Mine has done it too since day one. Always in low speed with torque on tranny (going up steep hill slow and pressing in clutch reproduces it almost 100% of the time.

scythezo6 01-07-2012 03:08 PM

I've had this since day one. Its super annoying you just have to adapt and learn to shift to avoid it. I slip sometimes and have that paddle sound at low speeds in 1st and 2nd but if you let off the clutch slower it avoids it. Even when stopped. Roll the windows down and put the car in neutral and press/depress the clutch pedal quickly and you hear it.Super annoying though.

jtvst4 01-07-2012 07:31 PM

mine does it too....when coasting down a hill very slowly in 1st and then pressing in the cluth. Seems as if it only doesit when there is "drag" on the tranny, such as going slowly up a hill, or coating down a hill slowly.

One of those quirks of this particular transmission.

Years from now, it will be affectionally mentioned on Mecum auto auctions.

Same here. Researched when I first got it and found it to be normal.

My 5th 01-07-2012 11:31 PM

My M6 does the clunk thing. I have a hard time accepting it as "normal"

Saying "...every six-speed I've had does it..." doesn't make it right. It's lame-ass engineering.

NONE, I repeat NONE, of my other manual transmission cars--of different makes--Corvette included, did this. But then, none of them had 6-speed transmissions. This is not progress, but stepping backward. How is it cars from the 60's 70's and 80's can be manufactured without this clunk, but today's computerized modern marvels can't?

I don't get it and guess I never will.

clutch noise
 
thanks. saved me trip to a dealer.

napalm0666 06-28-2012 05:17 AM

I got the same on euro model. It's degrading driving experience so much that sometimes I have a feeling that I'm driving some falling apart old crate not the brand new sports car....
How sorry I am now for buying a manual shifter car!
So, as I understand from all your posts, it's completely normal and there is no hope of fixing it?
:facepalm:
Is it worth trying to change a car while it's still new for a automatic transmission model?
